Research Abstract

In order to elucidate the experimental knowledge relating a direct electro-deposition of Ti metal from TiCl4, i.e. from the molten mixed TiCl2-KCl-NaCl salt, whereby TiCl4 gas bubbles are introduced and reacted with Ti electrode, thus continuously forming TiCl2 in molten KCl-NaCl mixed salt, the following experiments have been conducted; 1) TiCl4 dissolution rate, 2) TiCl2 formation rate in molten KCl-NaCl salt, 3) electrochemical requirement of Ti electro-deposition from TiCl2 in the mixed salt, and 4) direct Ti electro-deposition from TiCl4. The following experimental result has been observed or obtained; firstly, metallic Ti metal deposit is obtained, where it depends on TiCl4 feed concentration, bubble Ti electrode contact scheme and electro-current density and secondly, de-H2O and O2 from the molten salt are far important in this Ti deposition scheme.
